Description

  The present invention relates to a terminal connector, and more particularly, to a terminal connector for flexible aggregate wiring.

  For wiring used for interconnection of electronic devices, etc., a flexible flat cable (hereinafter also referred to as “FFC”) or a flexible wiring board (hereinafter also referred to as “FPC”) is used to improve flexibility in the wiring route. Such flexible aggregate wiring is used.

  For example, the FFC is formed by sandwiching a plurality of arranged foil-shaped conductors with an insulating film, and provided with terminal portions for connecting to other electric circuits at both ends thereof. In addition, the FPC includes a terminal portion formed of a plurality of foil-like conductors on the edge of the substrate in order to connect the electric circuit formed on the flexible substrate to an external electric circuit. Such flexible concentrated wiring is normally connected to an electric circuit via a detachable connector.

  However, since the flexible integrated wiring has low rigidity at the terminal portion, it may be deformed by insertion resistance or the like when connected to the connector, resulting in insufficient insertion or the like. For this reason, the flexible aggregated wiring is connected to the connector via the terminal connector by attaching the terminal connector to the terminal unit (for example, see Patent Document 1).

  For example, a flexible aggregated wiring terminal connector disclosed in Patent Document 1 includes a slider having a mounting part for mounting a terminal part of the flexible integrated wiring and engaging parts provided at both ends of the mounting part; A cover member that has an engaged portion that can be engaged with the portion and presses the terminal portion of the flexible aggregated wiring toward the placement portion side of the slider. The flexible aggregated wiring is configured such that the terminal portion is placed on the placement portion of the slider, and the engaged portion of the cover member is engaged with the engagement portion of the slider so that the terminal connector is pressed against the cover member. Installed.

JP 2006-85889 A

  By the way, the above-mentioned terminal connector may be used by bending the flexible aggregated wiring after mounting the flexible aggregated wiring depending on the state of installation in the unit, the usage method, or the like. In this case, bending occurs in the flexible aggregated wiring. When bending occurs in the flexible aggregated wiring, the adhesion between the slider and the flexible aggregated wiring decreases, and the reliability of the electrical connection of the flexible aggregated wiring at the time of connection to the connector decreases. Further, in the interconnection with the counterpart connector, there is a risk of causing a fitting failure.

  To cope with this, for example, it is conceivable to increase the thickness of the cover member that presses the flexible aggregate wiring so that the flexible aggregate wiring does not bend, thereby improving the rigidity of the cover member. However, the thickness of the cover member is limited when it is attached to the connector. For this reason, it is often difficult to set the cover member to an appropriate thickness.

  An object of this invention is to provide the terminal connector which can suppress the bending of flexible concentrated wiring.

  The present invention is a terminal connection tool for connecting a terminal portion of a flexible aggregated wiring to a connector, and a mounting portion on which the terminal portion of the flexible aggregated wiring can be mounted; A first member having an inclined portion formed at a rear end portion located in an extending direction in which the placed flexible aggregated wiring extends, a pressing portion formed so as to be capable of pressing the terminal portion, and A bent portion formed along the inclined portion of the first member, formed at the rear end portion located in the extending direction in which the flexible aggregated wiring is placed with the terminal portion placed on the mounting portion; The second member has a state in which the pressing portion presses the terminal portion and the bent portion bends the flexible aggregated wiring along the inclined portion. It is formed so as to be attachable to the first member. A terminal fitting to be.

  Moreover, it is preferable that the 1st rib part which can press the said flexible concentrated wiring which mounted the said terminal part in the said mounting part is formed in the front-end | tip of the said bending part.

  The engaging portion of the first member is formed in a substantially cylindrical shape, and the engaged portion of the second member is configured to rotate the second member around the engaging portion. It is preferable to be formed so as to be engageable with the joint portion.

  According to the terminal connector of the first aspect, the second member includes a pressing portion capable of pressing the terminal portion of the flexible aggregated wiring and a bent portion formed along the inclined portion. The second member is formed by the pressing portion and the bent portion so that a cross section in a direction orthogonal to the longitudinal direction is substantially L-shaped. Therefore, the rigidity of the second member in the longitudinal direction can be improved. Thereby, the bending in the longitudinal direction of the second member can be suppressed. As a result, it is possible to press the flexible aggregated wiring in a state in which the flexure is suppressed (a state in which the rigidity is improved), and the flexure of the flexible aggregated wiring can be suppressed.

  The bent portion of the second member is formed along the inclined portion of the first member when mounted on the first member. Therefore, the flexible aggregated wiring can be bent into a crank shape by the pressing portion and the bent portion of the second member and the inclined portion of the first member. As a result, the flexible aggregated wiring is less susceptible to the influence before and after being bent into a crank shape. As a result, for example, even when wiring or the like is performed in a bent state on the rear side bent into a crank shape, the occurrence of bending of the flexible aggregated wiring due to the bending on the front side bent in the crank shape is suppressed. be able to.

  According to the terminal connector of the second aspect, the first rib portion is formed at the tip of the bent portion. Therefore, the terminal connector can press the flexible aggregated wiring at the first rib portion. Thereby, the terminal connector can improve the holding performance of holding the flexible aggregated wiring. As a result, it is possible to make it difficult for the terminal portion of the flexible aggregate wiring to bend due to the bending of the flexible aggregate wiring.

  According to the terminal connector of the third aspect, the second member is rotatably mounted on the first member around the engaging portion. Therefore, the second member can be rotated around the engaging portion by utilizing elastic return deformation against bending of the flexible aggregated wiring. Thereby, the terminal part of a flexible concentrated wiring can be pressed with the rotational force by this elastic return deformation. As a result, it is possible to suppress bending of the flexible aggregated wiring.

Further, the slider rib portion 27 is formed so that a notch portion 140 formed in the terminal portion 110 of the FFC 100 can be disposed when the FFC 100 is disposed in the slider body 20A (see FIG. 9).

  In addition to FIGS. 7 to 9, as shown in FIGS. 11A to 11D, the cover member 3 </ b> A includes a pressing portion 31 capable of pressing the FFC 100 placed on the placement portion 22, and the slider body 20 </ b> A. A pair of arm portions 32A and 32A that can be engaged with each other, a bent portion 33 formed along the inclined portion 24 when mounted on the slider body 20A, and a slider rib portion 27 formed on the slider body 20A can be disposed. And a mounting restricting portion 37 formed on the surface.

  The pair of arm portions 32A, 32A are suspended from both ends in the longitudinal direction of the pressing portion 31 (the width direction of the terminal portion 110) along the side surface of the slider main body 20A. The pair of arms 32A and 32A engages with a substantially cylindrical engaging portion 23A formed on the side surface of the slider body 20A, and is engaged so as to be rotatable about the engaging portion 23A. 34A is provided. The engaged portion 34 is formed through the arm portion 32A so as to be engageable with the engaging portion 23A protruding from the side surface. Part of the engaged portion 34A is formed in a substantially circular shape so that the cover member 3A rotates around the engaging portion 23A formed in a substantially cylindrical shape.

  The mounting restricting portion 37 is formed at a position adjacent to the bent portion 33 on one end side in the longitudinal direction of the pressing portion 31. The mounting restricting portion 37 is formed so that the slider rib portion 27 of the slider main body 20A can be disposed when the cover member 3A is mounted on the slider main body 20A (see FIG. 13 described later).

Next, the operation of the terminal connector 1A according to the second embodiment will be described with reference to FIGS. 12 to 13B.
FIG. 12 is a cross-sectional view illustrating the operation of the terminal connector 1A according to the second embodiment of the present invention. FIG. 13A is an external perspective view for explaining the operation of the terminal connector 1A according to the second embodiment. FIG.13 (b) is the elements on larger scale of the terminal connector 1A shown to Fig.13 (a).

  The process until the cover member 3A is fixed to the slider main body 20A is the same as that of the first embodiment, and the description thereof is omitted here. As shown in FIGS. 13A and 13B, the terminal connector 1A includes a slider rib portion 27 in the slider body 20A, and a mounting restriction portion 37 in which the slider rib portion 27 can be disposed on the cover member 3A. Prepare. Therefore, for example, if the notch portion 140 formed in the FFC 100 is placed on the slider rib portion 27 and the terminal portion 110 is not placed on the placement portion 22, the FFC 100 interferes with the slider rib portion 27, and then The cover member 3A is configured so that it cannot be attached to the slider body 20A.

  When the cover member 3A is fixed to the slider body 20A, the terminal portion 110 of the FFC 100 is held by the cover member 3A while being pressed by the pressing portion 31, as shown in FIG.

  On the other hand, the FFC 100 continuous with the terminal portion 110 is bent into a crank shape by the inclined portion 24 of the slider main body 20A and the bent portion 33 of the cover member 3A (first crank bent portion 120). Similarly, the FFC 100 is bent in a crank shape by the end portion of the bent portion 33 of the cover member 3A and the guide portion 25 of the slider main body 20A (second crank bent portion 130).

  At this time, an elastic return force is generated in the FFC 100 to return from the folded state to the original state (flat state). This elastic return force acts in the direction of the arrow G1 shown in FIG. 12, and presses the bent portion 33 in the direction of the arrow G1.

  Further, the cover member 3A is attached to the slider body 20A so as to be rotatable about the engaging portion 23A. Therefore, the cover member 3A rotates around the engaging portion 23A by the elastic return force of the FFC 100. When the cover member 3A rotates about the engaging portion 23A, the bent portion 33 moves in the direction of the arrow G1, and the pressing portion 31 moves in the direction of the arrow G2. When the pressing unit 31 moves in the direction of the arrow G2, the pressing unit 31 further presses the terminal unit 110.

  The pressing force at this time increases as the elastic return force by the FFC 100 increases. For example, when the FFC 100 is bent upward as shown in FIG. 12, the force (arrow G1 shown in FIG. 12) that the FFC 100 pushes the bent portion 33 increases. Thereby, the force in which the press part 31 presses the terminal part 110 becomes large, and bending is suppressed.

  On the other hand, for example, when the FFC 100 is bent downward as shown in FIG. 12, the cover member 3A is pulled downward, and the force that the cover member 3A tries to rotate increases. Thereby, the force in which the press part 31 presses the terminal part 110 becomes large, and bending is suppressed.

According to the terminal connection tool 1A according to the second embodiment having the above configuration, in addition to the same effects as the terminal fitting 1 according to the first embodiment, the following effects.
In the terminal connector 1A according to the second embodiment of the present invention, the cover member 3A is rotatably mounted on the slider 2A (slider body 20A) around the engaging portion 23A. Therefore, the cover member 3 </ b> A can be rotated around the engaging portion 23 </ b> A using an elastic return force (elastic return deformation) with respect to the bending of the FFC 100. Thereby, the terminal part 110 of FFC100 can be pressed with the rotational force by this elastic return force. As a result, bending of the FFC 100 can be suppressed.

  Further, the slider 2A (slider body 20A) of the terminal connector 1A according to the second embodiment includes a slider rib portion 27 on the back side where a notch portion 140 formed in the FFC 100 can be arranged, and the cover member 3A is bent. The part 33 is provided with a mounting restricting part 37 on which the slider rib part 27 can be arranged. Therefore, when the FFC 100 is attached to the terminal connector 1A, if the FFC 100 is mistakenly arranged on the slider 2A (for example, reversely arranged), the slider rib portion 27 interferes with the FFC 100 when the cover member 3A is attached. As a result, the cover member 3A cannot be mounted on the slider 2A. As a result, it is possible to prevent the FFC 100 from being erroneously attached.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above. In addition, the effects described in the embodiments of the present invention only list the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention.

  For example, in the present embodiment, the FFC 100 has been described as the flexible aggregated wiring. However, the present invention is not limited to this. The terminal connector 1, 1A can also be used for flexible aggregate wiring such as FPC.
